Be warned, this is not for the faint hearted! Journey deep into the heart of a Welsh mountain for an extreme adventure and experience a whole new world - all while taking on epic challenges. Meet a seasoned guide for a briefing, get kitted out, then embark on a jaw-dropping journey which involves exploring secret subterranean tracks, tackling tough traverses, crossing decaying ancient bridges, climbing unspoiled rock faces, abseiling, whizzing down the planet's longest and deepest underground zip line - and last but not least, braving the world's first underground freefall. Stand at the edge of the ledge and plummet into a 70 foot abyss, falling at unbelievable speeds. No need to panic, the brake is applied before you reach the ground!
Daily throughout the year, excluding the 21 December to 27 December and New Years Eve.
